To be honest I think most of the boiler manufacturers will sell you a sight glass assembly complete with a length of glass tube. You can cut them to size very carefully with a dremel to fit exactly your own needs.

I would give John Hemmens a ring, Maccsteam, PPS Steam Models, Historic Steam Models etc but start off with this outfit here:

Current Range

The tube OD is obviously designed to fit the unions so I have no idea what it's size is.

I agree with soldering on the threaded bushes but use silver solder as you need the strength and heat resistance for the job.

Don't forget all this will then have to be pressure tested and certificated when you have finished before you will be able to use it in public or obtain insurance via a club.
